We collect and display a diversity of plants and trees for evaluation and educational purposes, in order to convey sustainable plant choices recommended for our region. By sustainable, we mean plants that are adapted to our soils and climatic extremes, free from chronic diseases and significant pests, and non-invasive of natural areas. Plants include rhododendrons, magnolias, maples, conifers, nut trees, wildflowers, lilacs and viburnums. A visitor center, reference library and picnic area are on the grounds. Holden connects people with nature for inspiration and enjoyment, fosters learning and promotes conservation.
